User settings
You can adjust the output state and settings when the power supply is on. You can also set the
beeper, navigation wheel (knob) state, and communication port in this menu.
Restore last output state on power up
This setting specifies whether the Series 2230G returns to the output state it was in before the power
was last turned off. If you select On for the output recall function, the Series 2230G restores the
output to the last state it was in before the power was turned off.
For example, if the output is turned on when the power supply is turned off or loses power, the output
returns to the On state when the power supply is turned back on or power is restored. If you select
Off, the output channel is always set to off after power is restored.
To enable or disable this function:
1. Press the Menu key.
2. Use the arrow keys to select User settings.
3. Press the Enter key.
4. Select Output Recall.
5. Press the Enter key.
6. Use the arrow keys to select On or Off.
7. Press the Enter key.
8. Press the Esc key to exit the menu.
Save last
This setting specifies whether the power supply saves its most recent settings (for example, voltage
and current) and restores these settings when turned on again. If you select On, the power supply
restores the instrument to the state that it was in before the power was last turned off. If you select
Off, the factory default settings are applied (1 V and 0 A for each channel).
To enable or disable this function:
1. Press the Menu key.
2. Use the arrow keys to select User settings.
3. Press the Enter key. Output Recall is displayed.
